Will more than one person receive founder equity in exchange for building the business?

A solo owner and a multi-founder team face very different splitting, vesting, and dispute risks - this routes the whole analysis.

Is any founder receiving equity mainly for money, property, or intellectual property already contributed, rather than for future work?

Equity for a past cash or asset contribution is a capital event; equity earned by working over time is treated very differently for both tax and vesting.

Split by contributed capital and value the property and IP transfers with a CPA.

Will one or two founders clearly carry most of the ongoing work, or hold the original idea, key relationships, or funding?

A lopsided contribution rarely justifies an equal split; naming the imbalance now is far easier than renegotiating after the business has value.

Do you intend to raise outside investment or grant an employee option pool within the next few years?

If money and options are coming, founder shares should be corporate stock with a clean cap table - LLC membership units make later financing and option grants far harder.

Issue restricted founder stock with vesting and file 83(b) elections within 30 days.

Could the team survive one of the working founders leaving in the first year or two without losing their full stake?

Without vesting, a founder who quits early keeps every share issued - the single most common and most damaging founder-equity mistake.

Put the agreed split in an operating agreement with buy-back and transfer restrictions. Add founder vesting and a buy-back right before any equity is issued.

Do you expect to bring on a co-founder, key hire, or investor who would receive equity within the next couple of years?

A sole founder's split is trivial today, but the choices you make at formation decide how cleanly you can add owners later without over-diluting.

Authorize extra shares and reserve an equity pool before you need to grant it. Take full ownership now and keep a simple cap table you can expand later.
